STOVE-Pl PE RETAINER.

SPECIFICATION forming part of Letters Patent No. 255,836, dated April 4,1882.

Application filed January 18, 1882. (No model.)

To all whom it may concern:

Be it known that I, ALFRED 0. Bmcres, a citizen of the United States,residing at Golumbia City, in the county of Whitley and State ofIndiana, have invented a new and useful Stove-Pipe Retainer, ot'whichthe following is a specification.

My invention relates to the application and use of certain mechanicaldevices for the purpose of retaining stove-pipes in proper posithemechanism illustrated in the accompanying drawings, in which- I Figure lis a view in perspective of my stove-pipe retainer, shown separate andapart from the pipe and. flue in connection with which it is used; andFig. 2 is a vertical section, showing the retainer in use in connectionwith the stove-pipeand flue or chimney.

Similar letters refer to similar parts in both figures. l

The retainer, Fig. 1, is usually constructed of a piece of hoop'ironabout one-sixteenth of an inch in thickness, three-fourths of an inchwide, and as long as the thickness of the fluewall may render necessary.This piece of iron is split at one end about one inch, and one side orhalf is turned up to form the upper flange, E, and the other half isturned down to form the lower flange, H. The main portion S of theretainer is as long as the thick ness of the flue-wall may require, andon its outer end is formed the loop K, on the under side of theretainer, corresponding with lower flange, H, as shown. It is intendedthat the distance between the inner edges of loop K and flange H shallcorrespond with the fluewall where the pipe is inserted.

A, Fig. 2, represents the walls of the flue or chimney, and B the spaceor hollow within the same.

0 represents the stove-pipe inserted in the stove-pipe hole in the flue.To the lower outer surface of pipe 0 is riveted the loop L at aconvenient distance from the inner end of the pipe, as shown.

The practical application of my invention is as follows: The retainer isfirst placed at the inner and lower side of the stove-pipe hole, thethickness of the flue-wall filling the space between flange H and loopK, with flange E pointing upward, as shown. The stove-pipe is theninserted until its end touches flange E. A wire, 0, is then passedthrough loops K and L, which are then drawn toward each other asforcibly as may be desired by twisting the ends of the wire together.After the parts described are placed in the relative positions indicatedit is plainly evident that the pipe cannot pass any deeper into theflue, because it is stopped by the flange E of the retainer, whichlatter cannot pass any deeper into the flue, because it is prevented byits loop K striking against the flue-wall. Neither can the pipe bewithdrawn from the flue, because its loop L is, by means of wire0,1irmly attached to loop K of the retainer, which cannot be withdrawnfrom the flue, because it is prevented by its flange H coming in contactwith the inside ofthe wall ot'theflue, as shown.

it is well known that large numbers of destructive fires are caused bythe ordinary careless modes of putting up stove pipes, there being undersuch modes no absolute certainty that the pipe may not slip out of thehole at almost any time, or slip into the flue so far as to interrupt orentirely check. the draft or communicate tire to the soot in the flue.

By the application and use of my invention the dangers and annoyancesreferred to are all efl'ectually avoided by constantly retaining thepipe in its proper position, as herein described and illustrated.

I claim as my invention- 1. In combination with a stove-pipe andchimney-flue, the retainer, as described, having upper flange, E, lowerflange, H, and loop K, substantially as set forth.

2. The combination of pipe 0 and loop L, wire 0, loop K, flange E, andflange H with flue-wall A, all substantially as described, and for thepurposes specified.
